You didn't rip a pin off because you used thin enough solid wire, as I advised back in reply #55.
All I can say about your soldering without being cruel is: Solder joints are meant to be shiny and have generally concave fillets that 'blend' where they meet the wire, pin or pad, not be grey and blobby. The latter are signs of a 'dry' (bad) joint, too much solder and either movement while it cooled, not enough heat or a lack of flux, maybe due to carrying
* the solder to the joint on the bit so the flux core burnt off before it got there - Always apply the solder to the work, never to the bit (except after wiping it, the bit needs a tiny drop put on it for good heat transfer).
However if it works, best to leave it for now. I strongly recommend practicing adding mod-wires to scrap boards, and also removing and replacing components on them to improve your skills before you work on anything valuable. The time to learn is *NOW* so don't wait till you desperately need the skills.
* Carrying solder on the bit for as short a time as possible is permissible, indeed necessary, for certain specialist techniques (e.g. drag soldering) but *ALWAYS* with extra electronics grade flux pre-applied to the work.
